The essentials
- Definition: the placement is where an ad is displayed: Facebook feed, Instagram Stories, Reels, Messenger, Audience Network, right-hand column… Automatic placements let the platform spread the budget across all of them; manual placements restrict the list.
- 2026 recommendation: automatic by default (Advantage+ at Meta), because the algorithm buys the cheapest impressions for the objective; manual by exception, to exclude what degrades quality.
- The frequent exclusions: Audience Network, right-hand column, Messenger for sales, placements with no suitable creative.
- The rule: decide on the cost per result by placement, not on the CPM.
When you create an ad set on Meta, LinkedIn or TikTok, the platform offers to choose the placements : the places where the ad will be displayed. By default, it recommends automatic placements and delivers everywhere it thinks it can get the cheapest result. Many advertisers restrict them by reflex; that is sometimes justified, often counter-productive. This article defines placements, lists them, explains what automatic does, when to take back control and how to read the results. Campaign structure is described in Meta Ads Manager.
The available placements
| Platform | Main placements | Notes |
|---|---|---|
| Meta | Facebook and Instagram feeds, Facebook and Instagram Stories, Facebook and Instagram Reels, Instagram Explore, Marketplace, in-stream video, Messenger (inbox, Stories), Facebook right-hand column, search results, Audience Network (third-party sites and apps), Threads | Around twenty placements; each format has its own dimensions and safe zones |
| LinkedIn feed (desktop and mobile), messaging (Message and Conversation Ads), LinkedIn Audience Network (third-party sites and apps) | The audience network should be switched off in most cases | |
| TikTok | TikTok feed (For You), TikTok Search, Pangle (third-party apps), group apps (CapCut, Lemon8) | The TikTok feed concentrates the value; keep an eye on Pangle |
| Pinterest, Snapchat | Feed, search, Stories, partner networks | Same logic |
What automatic placement does
- It buys at the lowest price: the algorithm delivers on the placements where the target result (conversion, lead, view) costs the least at a given moment; Stories and Reels often have lower CPMs than the feed, and the Audience Network lower still.
- It allocates dynamically: the budget moves from one placement to another depending on competition and the time of day.
- It adapts the creative if you have supplied it in the right ratios (1:1 feed, 9:16 Stories and Reels) or through per-placement customisation; otherwise it crops, often badly.
- It optimises on the result, not on perceived quality: a placement that produces cheap but poorly qualified leads will be favoured, unless you measure qualification.
On conversion objectives with reliable measurement and creative in every ratio, automatic generally does better than manual: more inventory, less saturation, a better cost per result. Meta's tests and advertiser feedback converge on a gain of 5 to 15%.
When to take back control
| Situation | Manual action | Why |
|---|---|---|
| Numerous but unqualified leads coming from the Audience Network | Exclude the Audience Network | Accidental clicks in apps, forms filled in by mistake |
| Sales objective, text-based creative | Exclude the right-hand column and Messenger | Low conversion rate, unsuitable formats |
| No vertical creative | Exclude Stories and Reels until a 9:16 is produced | A square visual cropped to vertical is unreadable |
| B2B campaign on LinkedIn | Switch off the LinkedIn Audience Network | Loss of professional targeting, degraded quality |
| Test of a specific format (Reels only) | Dedicated ad set in manual, with native creative | Isolate performance |
| Brand with strict context requirements | Placement exclusions and block lists (brand safety) | Avoid inappropriate content on the third-party network |
| Long video content | Favour in-stream and the feed | Stories cut off at 15 s |
The rule: start on automatic, read the breakdown by placement after two weeks, then exclude what degrades the cost per qualified result, rather than restricting from the outset.
Reading results by placement
- In the manager, break down by “Placement” (Meta: Breakdown, By delivery, Placement).
- Compare the cost per final result (qualified lead, purchase), not the CPM or the CTR: the placements with low CPMs (Audience Network, right-hand column) often have the worst costs per result.
- Check quality downstream: lead qualification rate in the CRM, session conversion rate in GA4 by placement (via UTM with the placement parameter); see sources, mediums and UTMs.
- Exclude the placements whose cost per qualified result exceeds the target over two weeks.
- Check that each placement kept has suitable creative; otherwise customise it by placement.
Creative by placement
Automatic placements assume creative for every format: square or 4:5 for feeds, 9:16 for Stories and Reels with safe zones, 16:9 for in-stream, short text for Messenger. Meta lets you customise image, video and text by placement group within the same ad: use it systematically. An automatic campaign with a single square creative loses most of the benefit. The formats are detailed in high-performing visuals and videos for ads.
The frequent mistakes
- Restricting everything to the Instagram feed “because that is where our customers are”: high CPM, rapid saturation.
- Leaving the Audience Network on a lead campaign without measuring qualification.
- Judging placements on CPM.
- A single creative for twenty placements.
- Never reopening a placement excluded two years ago: inventories and formats change (Reels, Threads).

Frequently asked questions
Should you choose automatic or manual placements?
Automatic by default: the algorithm buys the cheapest impressions for your objective and avoids saturation, with a gain of 5 to 15% on the cost per result in most tests. Switch to manual by exception, to exclude the placements that degrade quality (Audience Network, right-hand column) after reading the results.
Should you exclude the Audience Network?
Often, on lead and sales objectives: this network of third-party sites and apps produces accidental clicks and poorly qualified leads at low cost, which mislead optimisation. Check the cost per qualified result by placement; if the Audience Network is clearly worse than the feed, exclude it. It can still be useful for awareness.
How do you adapt creative to placements?
Supply a visual or a video per ratio: 1:1 or 4:5 for feeds, 9:16 for Stories and Reels respecting the safe zones, 16:9 for in-stream. Use the platform's per-placement customisation within the same ad rather than letting it crop automatically.
Are placements read on CPM?
No. The placements that are cheapest on CPM (Audience Network, right-hand column) often have the highest costs per qualified result. Break down by placement on the cost per qualified lead or per purchase, and check quality downstream in the CRM or GA4 before excluding or keeping.
